Page 15 is the end of index page which finishes in the middle of the said page & page 16 is left blank intentionally, As you will find it in many books. And the first " addhyay" that is chapter 1 starts right after intentionally left blank page which is in fact page one and so on.

So we aren't missing on " Bhagvadgeeta".

Hopefully this helps!

Firstly, thank you to whoever has uploaded this book. Thanks a ton!! However, I just started reading this book and have noticed that pages 15 and 16 are missing. It is an absolutely great book however, the missing pages interrupted my interest. It would be great if someone could upload another copy without any missing pages. I am not sure if there would be any more missing pages ahead. No offense please. Just mentioned because its hard to miss on such great info and move ahead.
Thanks!

Very compressive and thorough .one can get all required details and references.
